Dewey Norris of Mulberry is accused of placing a pen camera in his bathroom to record four female victims he had access to, while they undressed.

Investigators said the victims were 14, 15, 16 and 19 years old.

Authorities said a friend of Norris' discovered 53 separate videos of nude girls on seven different DVDs. The friend immediately contacted authorities when he discovered the clips.

Norris admitted to placing the hidden camera into the bathroom prior to each girl going in, and then retrieving it afterwards, and viewing the videos for his own sexual gratification, according to a news release.

Officials said Norris' face can be seen in the videos while he placed the camera in the bathroom.

The victims told detectives that they were all unaware that they were being filmed and that they were not sexually abused by Norris, the report said.

Detectives seized five computers from Norris' home, including three desktops and two laptops, as well as two cellphones.

Investigators said Norris told them he completely destroyed the camera, according to the release.

Norris is charged with four counts of video voyeurism of a child over 16 and 49 counts video voyeurism of a child under 16, as well as one count destroying evidence.

Norris told detectives he has been employed by the Hillsborough County School Board for over 20 years as an air conditioning unit mechanic.
